  • Automation can't beat iteration

• Which tool for what?

  • Paths abstract acceleration from position
    • Ex: tracing a finger over a surface
  • Drivers coordinate many bones easily
    • Ex: fingers, eyelids
  • Constraints translate between spaces
    • Ex: world-space FK head
  • Only expressions know about time
    • Ex: Schedulers
